CCPaSEC has produced several videos intended to give viewers an opportunity to see what our stream monitoring entails as well as training videos which are intended as training tools for our members.  CCPaSEC teams use Hach test kits, Oakton PCSTestr35 5-Function Meters,   Hach DR850 Colorimeters, YSI Model 550a Dissolved Oxygen Meters, and Hanna Model HI 9146 DO Meters in monthly water testing.  The videos describe how we measure dissolved oxygen, nitrates, sulfates, and phosphates as well as how we conduct our macroinvertebrate surveys.
